The cost? $35,000.

If you travel regularly to London or Paris—or would like to start doing so immediately—consider this offer from the business-class-only airline, La Compagnie.

To celebrate its second anniversary, La Compagnie is selling 10 memberships for a year’s worth of unlimited flights. The all-you-can-fly-passes, L’Unlimited, won’t come cheap. You’ll have to make a one-time purchase of $35,000 in order to secure your pass. And no, you can’t put the monthly installments on your credit card.

Each L’Unlimited is valid for 12 months from your first flight (which you must take by December 15, 2017), and flights can be canceled up to three hours before departure for no fee. A personal concierge will also be available to make all of your bookings.

At this time, La Compagnie operates two Boeing 757s, with a third on its way, between Paris, London, and New York City. Every seat onboard is fully lie-flat, and travelers can enjoy everything from entertainment on Samsung tablets to Caudalie cosmetic kits. Michelin-starred Chef Christophe Langrée crafted the onboard menu.

La Compagnie will sell only 10 of these unlimited tickets on a first come, first serve basis starting July 18.

So just how often do you have to fly to Paris or London to make this membership worthwhile? With flights beginning at $1,600 (from Newark to London) that’s 22 flights—or about one round-trip vacation, family reunion, or business meeting per month.

Believe it or not, L'Unlimited isn't the most expensive ticket you can buy. The world’s most expensive flight has a $38,000 price tag. And that’s just one-way.
